Rabi resonances induced by an offresonant, stochastic field
Abstract
When an atom interacts with a phasefluctuating field of fairly arbitrary spectral character, the Fourier spectrum of atomic population variations manifests a ``bright line'' at the atomic system's Rabi frequency. This bright line is termed a Rabi resonance. Here, we generalize our previous studies of this phenomenon by considering the characteristics of the Rabi resonance when it is excited by an offresonant stochastic field. We find both experimentally and theoretically that (i) the Rabi resonance occurs at the Rabi nutational frequency, Ω=Δ^{2}+ω^{2}_{1}, where Δ is the detuning and ω_{1} is the Rabi frequency, (ii) that the strength of the Rabi resonance is maximized when \Δ\ equals ω_{1}, and (iii) that the strength of the Rabi resonance is an asymmetric function of detuning.
